IMPRovED sAsH-BALANcE:

Be it known that I, WILLIAM STANrmLD, of Flora, in the county of Clay, and State of Illinois,have iui vented a new and useful Improvement in \Vindow-Sash fSupporters; and I do hereby decla-re that the following is a full, clear, and exact description thereof, which will enable others skilled inthe art to make and use the same, reference being had to the aceompanying'drawing, forming part of this specification.

-This invention relates to a new and improved method 'of supporting and operatin g the sashes of windows; and

consists in substitutin g for the single-pulley wheel usually employed, two shafts, inserted horizontally in the upper part of the frame, and centrally of the same, which are -each provided with a pulley within the frame, to which the inner and-outer sashes are attached, by suitable cords', and with a' pulley upon the outer side iof the frame, to which the outside operating-cords are attached.

By this arrangement, the line of direction of the weight of thefsash, and the power appliedto the same, are in a direct line. l v

When the pulleys are arranged only upon the outside of the' frame, as in the ordinary manner, and the operating-cords extend therefrom directly to the sashes, the latter are not raised in a direct line, but are caused 'to bind within the casing, which greatly retards their B is the window-sill.

C represents the lower sash.

D is the .upper sash.

c e represent two horizontal shafts in the top part of th trame, one shalt for each' sash. c is the shaft forthe lower sash, and c is the shaft. for the uppersash.

0n the outer ends oi' these'Ehaic-s are pulleys f f.

. g g represent c ords, which are attached to au'd wound around these pulleys, from whence they extend and pass around the small pulleys g g', on the front casing, and from thence down to the fastening-clamps It 71, as seen in the drawing: n

"Z'he Schedule referred. to in these Letters Patent -and making part oi the' same.

- Upon the back portioncf each ofthe shafts. c c are other pulleys, directly oyer their respective sashes',l

marked fi, one of which isseen in fig. 2.

J J represent cords, which 'are attached to these pulleys @and to the sashes, as seen in the drawing.

vThe operation willbe readily rnrderstood'ii'oni vthe drawing.

-. By pulling down on the cords y, thel shafts e o will he revolved, which will of course revolve the pulleys a', wind up the cords J, and-mise the sashes.`

When either 'of the sashes is suspended by its cords,- t-he upper' one would be raised by revokingthe shaftc and winding up the cord J, and be lowered by loosening its hand-cord 'g from` the clamp h. The other sash is operated in the same manner, only the motionsl are reversed. gravity, but raised by pulling down ori the cords gg.

It willbeseen thatthe clamps h gripe the cords. y in such a manner that any upward movement o1' strain only serves to tighten them.

They are loosened by pressing on tlie points 'k kA of the clamps.

The clamps h are each eonrposed'of alever, -pivoted within a suit-ablel keeper attached to the frame. The lower ends of these leversare inclined or bevelled, to correspond with the bevelled inteiior of the keeper, as shown in dotted lines, iig. 1, of the drawing, and their upper ends, k, extend wit-hout the keeper", as before mentioned. A

The sashes -(either of tlie1n)can thus`be heldin any desired position without`the use of weights.-

In fig. 2, L represents a bolt,.by which the' sashes are fastened together when' they are closed.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- In raising windows, substituting for the single-pulley wheel the shafts o e', arranged as described, and furnishedeach-with 011e pulley within the window-ti'ame and one without the same, to which the sash-operating cords are attached, so as to allow the line of direction of the weight of the sash andthe power applied thereto to be in a direct line, as herein shown and described for 'the purpose specified.

Theabove specification of my invention signed by me, this 24th day of February, 1869. W'ILLIAM SIANFIELD.
